Wigner flow reveals topological order in quantum phase space dynamics
Ole Steuernagel, Dimitris Kakofengitis, Georg Ritter
The behaviour of classical mechanical systems is characterised by their phase portraits, the collections of their trajectories. Heisenberg's uncertainty principle precludes the exi…

Double-Well Quantum Tunneling Visualized via Wigner's Function
Dimitris Kakofengitis, Ole Steuernagel
We investigate quantum tunneling in smooth symmetric and asymmetric double-well potentials. Exact solutions for the ground and first excited states are used to study the dynamics.…
